PLC通过输入/输出终端与控制对象相连。PLC的输入输出端通常有三种组织形式，即汇点式、分组式和分离式。PLC的输入端大多采用汇点式，部分PLC采用分组式，以增加使用的灵活性。
收集温度、压力、，并根据收集的数据对加热进行控制，达到了节能的目的。根据室外气候的变化，通过调整原管网电阀的开口，及时控制二次管网的回温。通过调度给定的控制曲线，每个换热站的运行参数是在给定的范围内。同事们，中央控制室根据需要，对调度的电阀进行远程控制，调整运行参数。gprs dtu系统配置，能实现温度控制，充填遥控水泵频率转换。上位机选择配置王配置软件，与数据库结合，存储分析有数据，并能配合优化软件进行优先级控制。
如何在ABPLC程序中实现模拟信号的质量判断。
1.设计主要解决AB PLC系统不能使用功能块来实现模拟信号的质量判断，充分利用PLC的一些简单功能块组成一个多功能组。
2。经过逻辑配置后，原系统不发生因信号不可靠而引起的停机，了系统的可靠性。
如何在abplc中找到交换变量
打开300的变量表，打开要在人机界面中关联的组件的属性，组件属性中有一个“变量”栏，您可以在其中选择变量300，或者从变量300的表中直接拖动需要关联到“变量”栏的变量。因此，PLC和人机界面的变量是自动关联的。这是一个相对简单的方法。
